Fitting for attachment to a piece of fabric

Abstract

A buckle part or fitting to be attached to a piece of fabric includes first and second parts adapted to be held in position by at least one post passing through the fabric, one of said parts being provided with a recess and the other part having a raised portion of somewhat smaller peripheral size than the recess, so the fabric will be compressed into the recess when the two parts are clamped together. The two parts are made of a material having high frictional properties, whereby the posts are self locking in their mating bores; in fittings subjected to heavy wear, an extra post adapted to be upset in its bore may be provided as a safety measure.

I claim as my invention: 
     
       1. A buckle having a portion for being attached to fabric, comprising: a. a first part having a side face for being disposed against one side of the fabric;   b. a second part having a side face for being disposed against the other side of the fabric;   c. at least one post extending from one of said parts for passing through the fabric into a bore in the other of said parts; and   d. a recess in one of said side faces and a raised portion of complemental shape on the other of said side faces extending about said at least one post and receivable in said recess, there being a peripheral clearance between said recess and said raised portion corresponding to the thickness of the fabric.   
     
     
       2. A buckle according to claim 1 in which said first and second parts comprise a synthetic resin having high frictional properties, whereby said post is retained in said bore. 
     
     
       3. A buckle according to claim 1 in which said post projects out of said recess into said bore in said raised portion. 
     
     
       4. A buckle according to claim 1 which includes at least two of said posts and bores located along a line substantially perpendicular to the direction in which the buckle is to be tensioned. 
     
     
       5. A buckle according to claim 1 in which said side faces have a rough finish. 
     
     
       6. A buckle according to claim 1 having an additional shorter post projecting from one of said parts into an additional bore in the other of said parts, said additional bore having a counterbore into which said additional post can project and which counterbore is receptive of an upsetting tool for acting on the free end of said additional post. 
     
     
       7. A buckle according to claim 6 in which at least two of said posts and bores which, along with said additional post and bore, are located on a line substantially perpendicular to the direction in which the buckle is to be tensioned. 
     
     
       8. A buckle according to claim 1 in which said recess has a depth greater than the height of said raised portion whereby the fabric can be positively clamped by the portions of said parts which surround said recess and said raised portion.
